Abstract
A method for packaging an organic light-emitting diode (OLED) display panel includes: providing a package cover and an OLED substrate, and an OLED device arranged on OLED substrate; simultaneously printing a circle of a support and a hydrophobic barricade on an outer side of the package cover corresponding to the OLED device by means of screen printing, the support printed on an outer side of the hydrophobic barricade; and cementing the package cover and the OLED substrate. The hydrophobic barricade can effectively prevent external water vapor and oxygen from touching the OLED device. Therefore, the effect of package is enhanced, and the lifetime of the OLED device is prolonged. Further, the support and the hydrophobic barricade are formed at the same time through screen printing. Not only the method is simple but the efficiency is enhanced.
